Several challenges affect Yakutia territory in the triple context of climate changes, increasing natural risks exposures, and massive urban transformations: metropolisation dynamics in Yakutsk, decreasing of populations in the Arctic settlements, multiple exposures of populations to the flooding, pollution, permafrost melting, etc. If the local...

Les petites villes, notamment en France, ont joué un rôle important dans la constitution des territoires métropolisés. Elles ont été successivement des espaces relais de l'exode rural en direction des grandes villes, pour une partie des territoires sur lesquels se sont appuyées les dynamiques d'externalisation de la croissance urbaine des...

This presentation presents the objectives, organisation, political decisions, and issues of the French Arctic Policy. A focus is made on the scientific interests and contributions to the Science-diplomacy.

The use of the remote sensing approaches for the analysis of the societies is one of the base fundamentals with the first applications in urban planning in 1856 on Paris. The questions of territorial and societal analysis, the building of socioeconomic geodatabases is considering since the 1960s as a strategic core for the States and...

Metropolitan planning policies are linked to the implementation of environmental transition items. Several approaches are being implemented, notably in organic carbon management and emissions. In terms of planning, they are constrained by geography itself, i.e. the complexity of geographical space, and its spatial, human, and territorial...

Neolithic monuments and burial sites can only be studied in their spatial context (Bowden et al. 2015; Sévin-Allouet 2016; Luc Laporte, López-romero, and Bernard 2015; Wunderlich 2019). The landscape and ancient monuments are sufficiently well preserved to give an overall view, and this is one of the major interests of the Grands Causses....

Le CES « Artificialisation - Urbanisation » du Pôle THEIA s'est donné pour objectif (i) de développer l'usage des outils, méthodes et données de télédétection appliqués à cette problématique, et (ii) de valoriser et qualifier les informations et favoriser leur appropriation par les usagers. Du point de vue applicatif, les enjeux sont d'assurer...

Some circumpolar regions as Yakutsk in the North Eastern Siberia are characterised by an emerging process of metropolisation. The emergence of large urban areas in Yakutsk increases the level of vulnerability of the population of the Lena's river debacle flooding. A spatial model based on remote sensing measures the level of urban population...
